To answer Tony Monte's original question:
Yes, the Colombo Bros. crew
did interact with other crime families. In fact, they held pseudo-sitdowns with the Bonanno and Lucchese families over their turf in upstate NY.
Who was in their crew? Were they brought back into the fold when Russo was bringing members back?
The crew was headed by Colombo soldiers Anthony Colombo and Gerard "Jerry Green Eyes" Clemenza. Colombo passed away in 2017, after moving to Los Angeles and writing a book about his father's murder and potential set-up. Clemenza, on the other hand, is a very wealthy racketeer in upstate New York who spends a considerable amount of the year in Sarasota IIRC. The third "leader" of the crew was Anthony Colombo's brother, Chris Colombo.
Now, all three of these leaders are/were living pretty comfortably, enough to indicate that they made
a lot more money than the average Colombo button man. If they were still active through 2010, one can assume that Andy Russo would have brought them into the fold.
